Originally I tried to separate the mere typographical errors, the
more substantial mathematical errors, and the addenda (i.e., things
that aren't actually errors, but just comments about what I wish I
could add to the book). But I've decided that it's not really possible to
separate those categories -- there's too much overlap.

For convenience this list is now broken into several web pages, one for
each "part" of the book:

In addition, the worst error was the
ERROR IN THE INDEX:
Now that the book has already been printed, I am horrified to discover
that many of my index entries are off by a few pages. Here is
a conversion table. In most cases,

If the page number in | Then you should
the index is between | increase that number by
-----------------------+-------------------------
1 and 430 | 0
431 and 571 | 1
572 and 673 | 2
674 and 834 | 3

You may find it helpful to tape a copy of
this table to the inside back cover of your book. Fortunately, most
terms appear in boldface when they first occur in the text, so
they're not hard to find.
